Greyhound Auto Retail stocks drills and drilling accessories including cordless drill drivers, impact drivers, hammer and rotary hammer drills, plus HSS, masonry, wood and specialist drill bits.

Match the machine to the material. A standard drill driver handles wood, plastic and thin metal. Masonry, brick and concrete need hammer action, and anything beyond light masonry work is far quicker with an SDS rotary hammer than with a conventional hammer drill.

Bit choice and technique do most of the work. Use HSS or cobalt bits on metal with a slow speed and firm, steady pressure plus cutting fluid, since running fast and dry is what burns the cutting edge off. Masonry bits want speed and hammer, wood bits want speed without it. Centre-punch metal before drilling so the bit does not wander.
